The sum of the interior angles of a 15-gon is (15-2)x180 degree which is 13x180 degrees or 2340 degrees.

If the 15-gon is a regular polygon, then: Sum of the interior angles = 180°(n - 2) = 180°(15 - 2) = 2,340° Each interior angle = 2340° ÷15 = 156°

If you are driving 2340 miles, based on a car that gets 15 miles to the gallon, take 2340 divided by 15. That is 117 gallons that you are going to need. 117 times $3 a gallon (depending on the price of gas) equals $350.00.

A polygon of 15 sides has interior angles that add up to 2340 degrees.
2340
It is 2340/15 = 156 degrees
(15-2)*180 =2340
